Extending AF_XDP with Hardware Metadata

Explore the advancements in AF_XDP, a packet family built on XDP, in this 22-minute conference talk from the Linux Plumbers Conference. Delve into the capabilities of AF_XDP for direct access to low-level networking queues from userspace, exposing raw packet headers and payload while bypassing most of the kernel stack. Learn about recent developments in NIC receive-side offload support and ongoing efforts to implement transmit-side offloads. Gain insights into current progress and future prospects for extending AF_XDP with hardware metadata, as presented by Stanislav Fomichev.
